When I returned home, I was full of feelings.

After crying and laughing, the family sat down at the dinner table and ate a hearty meal.

As an older sister, the gentleman looked at his brother's half-blind eye and thought of another thing about the eye.

After she came back from Chudi, she was now tidying up in the Xuxu University Hall for a period of time, and during that time, an extremely sensational thing happened in the University Hall.

Some people have poked their own eyes blind in order to find out the real reason why the human eye can see the colors.

Because Mozi has studied optics deeply, he has put forward the principles of optical eight-method and concave mirror convex mirror, as well as the problems of small hole imaging and light propagation along a straight line.

Therefore, as one of Mozi's "most important disciples", of course, he had to put this skin on his body well, so Sishang did a series of inventions such as the spectroscopic experiment of the prism and the telescope related to optics very early.

This can be regarded as a kind of good at the top, and it must be effective at the bottom. However, when it develops to a certain extent, there are really people who want to explore the principles of Tianzhi, so there are often all kinds of stories that make people sigh or laugh in the Xuxu University Hall.

Since sunlight is essentially seven colors, and everything is black without sunlight, how do human eyes perceive different colors?

So someone came up with a conjecture that the human eye is also a prism-like device.

According to the fact that the prism must have a special shape to divide the seven colors, and the human eye can see the seven colors of light, he conceived an experiment to verify whether his conjecture was correct.

Hypothesis...... The human eye also has a star that resembles a prism

To prove this, he poked his finger into his eye, the part under the socket, and squeezed it hard to deform it.

After poking hard a few times, I found that all kinds of fantastical colorful colors really appeared in my mind.

So, to prove it, he increased his power by a few points, often, and then recorded everything he observed.

As a result, one day I used too much force and poked too deeply...... The left eye was shattered.

After shattering, he finally came to a conclusion: the human eye is not something like a prism, but another reason causes the world to be colorful, as for what the reason is, there is no result for the time being, but it absolutely negates another possibility.

After this incident came out, it also led to a new rule issued by the Xuan Xuan Academy - prohibiting self-harm in order to explore the truth of the Heavenly Will.

Because there had been several terrible situations before this, risking one's own life to seek the so-called truth of providence, this eye-poking incident was just the fuse of the prohibition of self-harm.

Before that, some people tried the taste of various strange ores, recorded the feeling after taking it, and several people died.

Of course, he also left a few rather strange notebooks - for example, the phosphorus used in the witches who were poisoned to death in the Sishang obscenity incident, and after Solushen returned from his westward journey and brought back garlic, some people recorded that there was a smell of garlic after the phosphorus poisoning, and it was suspected that the phosphorus content in the garlic was very high.

As for how to draw conclusions, how to observe, it is another story of careful thought.

This kind of thing that looks too strange outside of Sishang, and even feels too strange outside of the Xuan order, is normal in the eyes of people in the circle such as the gentleman.

Mo said that Shu Guitian was blind in one eye, even this time he drew a geographical map of mountains and rivers, and several people died, and Shu Junzi felt that it was a blessing for his younger brother to come back alive.

In the midst of the staggering, the family drank a lot of wine.

Seeing that his younger brother had drunk a lot of wine and was still sober, he smiled and said, "Okay, I will only drink when I leave, and now I drink so much?" ”

Shu Guitian put down the white porcelain wine glass and said hesitantly: "At sea, we drink less water and drink more." Wine can live, but water can't. You don't know, the merchants in the South China Sea who went out to exchange Xuanlin beads for gold turned the bagasse in Panyu into wine. ”

Looking at the plate of bean sprouts on the table, Shu Guitian pointed to those bean sprouts and said, "As long as I go ashore, I won't eat a mouthful of bean sprouts." ”

The father smiled, and the mother's hand deftly changed the position of the plate of bean sprouts and replaced it with a plate of vermicelli stewed chicken.

After a few more glasses of wine, Shu Guitian looked at the gentleman and asked, "Sister, I haven't been able to figure it out, how did you draw that map?" I looked at the stars every night, and I had walked so far from here, and all the stars in the sky were about the same. The moon is about the same. We can also calculate the latitude, how do you calculate the longitude? ”

The word Jingwei naturally has been around for a long time, and these people in Sishang are also accustomed to it and take it for granted that it should be called so.

"Examination of Work" says, nine warps and nine latitudes; "Zuo Biography" also said that the longitude and latitude of heaven and earth are also.

Originally, it referred to the warp and weft of linen fabrics, which led to the north-south left and right roads, and when the cosmology of Sishang appeared, it borrowed the meaning of north-south, east-west and longitude and latitude.

The gentleman was extremely proud of participating in the drawing of the Kyushu map this time, but after thinking about it, he felt that it was too troublesome to explain to his younger brother, so he had to say, "You don't understand it." In short, Tai Sui Star can be the best water leak timer in the world. There are twelve hours in a day, and the longitude is different, and the hours are different, so it can be calculated. ”

"If you look at the height of the stars and the moon, you can tell what time it is at night. Looking at the position of the moon of Tai Sui Xing, it can be seen that Pengcheng is at this time at night. After a little calculation, you will naturally know the longitude of this place. ”

Speaking of this, she thought of one thing, looked at her younger brother with an eye patch, sighed, and said, "It's a pity." The fact that the earth under your feet is round, it seems that you don't have to go around the earth once. Longitude can be measured, and the distance per degree is smaller the further north you go. The earth is certainly not flat, but a ball. ”

None of the people present believed that the earth was flat, so Shu Guitian pondered for a moment and asked, "Sister, can your method of measuring longitude be used on the ship?" ”

The gentleman immediately shook his head.

"I don't need it. Even if you have a telescope, the moon of Tai Sui Star is too small to be seen if it is slightly bumpy, and it is always troublesome to calculate. But if it's on land, it can be calculated. ”

Only then did the family react and asked repeatedly, "Do you still want to go to sea?" ”

Shu Guitian nodded naturally and said, "Of course." When the world is one, I may have to go to sea often, and after the war, I will have to live. ”

The mother muttered, "You can't spend your money now." ”

This kind of money was exchanged for their lives, and the people who went to sea together at the beginning only came back a third, which still made all kinds of food and logistics preparations.

Of course, there are also many profits, not to mention the per capita share of one-twentieth of the Chamber of Commerce mentioned by Shu Guitian in the future, that is, this time one-fifth of the gold belongs to them equally, which is also a huge wealth.

Shu Guitian sighed when he heard this: "Who cares if there is more money and less money?" The world is so big, there will always be a record in the history books in the future, and my concubine Guitian also participated in the feat of the first voyage to India. Those who will be seafaring merchants must remember. ”

"It's just...... This time I was an intern, and most of the people remembered were our captains and representatives of the ink artists, but they couldn't remember me. ”

"I want to do something big and be remembered. Money...... I really don't care, because I don't lack it. ”

He glanced at the second brother who had been at home and said, "Second brother, why don't you go and register, and I'll find you something to do in the South China Sea?" As long as you are willing to play with your life, you will get rich. I have quite a few classmates over there. ”

Shu Zhuyue shook his head and said, "Forget it, I'm fine at home." Besides, I'm going, what about your sister-in-law and nephew? I don't want to go. Some of the village community went, some got rich, and some got sick and died. ”

Shu Guitian pouted and said: "I said a long time ago that when the giant gave us a name, we should change it." ”

He looked at the captive again and said, "Brother, before I left, I heard that the giant was interested in finding a place where his two masters said that sulfur, gold, silver, and copper were produced. And it's not far from us, have you found it? ”

Shu Prisoner nodded and said, "I found it." It's not far from Juli, just across the sea. But there...... It's not like the rich place you're going to this time. ”

"The people there are still using stones, not even slash-and-burn farming. I went with the Xuanlin beads and got back a bunch of clay pots, who wants to go? ”

"But there was a company of men left, and a small town by the sea. Recruited some fugitives from Qidi, and there were not many people, three or five hundred, who went over there. ”

"The merchants were reluctant to go, so they had to look for gold, copper, sulfur, and so on. But even if it is found, this mining is still a problem. ”

"The flotilla went a long way around the coast, and I heard that it was very large. Some tribes do have some gold in their hands, and they all pick it up in the water. They don't pan for gold. I've heard that I'm going to send someone to find the mine again for a while. ”

"In fact, as long as you find gold, silver, copper, or even sulfur, as long as someone mines it, there will definitely be more. But there's no one. ”

"Why do you ask this?"

Shu Guitian clapped his hands and said, "What are you doing?" This is an opportunity to leave a name in the history books! Brother! ”

"Think about it, back then, Panyu City, 800 people, 800 people took Panyu City. No matter how bad Panyu City is, there are still bronze vessels. What do you say is on that island? The tribesmen are still using stones, and they are still in the same way as they were before the Yan Huang in ancient times. ”

"As long as there are means, three hundred people are enough to cross such a large island."

"There will be fighting between tribes. Emperor Yan and Emperor Huangdi have also fought, if I take people to the island, it doesn't take too many, three hundred people are enough to do something big. ”

"Nobody mining? It's simple, what did you do when Sishang was first founded? Each village community takes turns to send people to serve in mining and digging ditches, is it possible that it can be used in Sishang, but it can't be used there? ”

"There are hundreds of thousands of people on a huge island, so there are still mines that can't be mined? Now the sulphur, the gold, the silver, and the copper, are all urgently needed. ”

"If you think about it, you don't need many people, three or five hundred, plus some craftsmen who can mine and prospect, it's enough. Juzi said that his two gentlemen knew that there was there, and that there was naturally there. Such a great feat......"

Speaking of this, Shu Prisoner staggered and patted his younger brother's shoulder and said, "Can you think of it, can you think of it?" It's not that simple. ”

"I have a friend who participated in the first expedition at the first camp, and there are a lot of things involved, but it's not as simple as you think."

"I'll just ask you, the land in Kyushu can't be planted yet, there is land in Huaibei and Jiangnan, and no one has gone yet, who will risk death to run to the island?"

"Not for gold and silver? But for the sake of gold and silver, gold, silver and copper are dug up, it must be managed from above, it is impossible to dig casually by private individuals, and even if you dig it, you have to have a kind of food, right? This is not something that can be done overnight. ”

"Indeed, those tribes are still using stones, but they are not a state like Panyu, but a primitive village community, the land belongs to the public, everything belongs to the public, there is almost no private ownership, and there is no organization. The people there in Panyu do have slaves, but even if they are slaves, after they are released, they also know how to listen to orders and know what they can and cannot do. Do they know what it means to obey orders? ”

"Mining...... People don't want to dig it, so it's a big deal to run to the mountains and drink blood, and they used to live like that. You have to find a way to get them to dig it, find a way to get them to accept it, you see...... The South China Sea is reluctant to ask for local 'long-term workers' in the South China Sea, why, because they are familiar with the environment of the South China Sea, what can they do if they run into the jungle? ”

"The above is also thinking about how to control it, not to make a mess, to spend less money, to employ fewer people, and to provide a large amount of gold, silver, copper, and sulfur. It's too complicated, it's not as simple as you think. If there really were a state like the states of the South China Sea, where the nobles divided the land, the cultivators had their own land, the world was equal, and the hearts of the people were attached, and the matter would be simpler. ”

"The members of the village community there are originally equal, the land is originally owned by the people of the world, and the wealth is more equal than the equal exchange that the peasants fantasize, how can we do it? Who's going to do it? Let those who want to seek personal gain and harm others, it is impossible for the above to agree that they are not willing to go to that kind of place, after all, there are many places to make a fortune in Sishang, and they will run to change clay pots? Let the ink people who have the world obey discipline and firmly believe in equality and love to do ...... The reason is unreasonable. ”
